ZnSe optical components

Zinc selenide (ZnSe) is the most popular material for infrared applications. Very wide transmission range covering 0.6 - 22 µm and high quality material grown by CVD technique (Chemical Vapor Deposition) make ZnSe a good material for manufacturing optical components (windows, mirrors, lenses) for high power IR lasers.
